Review: Great product - Remember that guy in Phoenix that died in someone's attic doing HVAC during the summer when it was one hundred and a billion degrees out? I was almost that guy. So I'm up in the attic, doing HVAC for the new addition on the house. Pretty straightforward stuff, and it's Phoenix. IT'S. ALWAYS. HOT. So attic heat - no problem. Well, in my infinite wisdom I purchased this product ahead of time. I'm going up there anyway, I might as well install some reflecto-barrier while I'm at it. Now - if you're going to be working in the attic, it's wise to lay down some boards to work on, instead of laying in fiberglass insulation. Let me tell you how much fun it is to go up there, sweat like a madman, have all your pores WIDE OPEN, and roll about in fiberglass. The itch is real people. So I figure - why not double my reflective capacity and put down the plywood with the reflective barrier already on it! Genius right? So there I am, up in the attic, 118 degrees outside, literally no airflow. I've got the radiant roof pouring heat in from outside. I've got plywood with reflecto-space-blanket coating underneath me. Might as well be a solar oven up there. I dropped 10lbs of water weight. I might have even seen Jesus. Somewhere in there just shy of dying from heat exposure I realize I've got this amazing shiny stuff that I need to staple to the rafters. I cut a slice, even the barrier from just sitting there is about 140-billion degrees. I'm feeling fortunate for my gloves... incredibly stupid for doing this in the summer... and not sure if I'm dead or alive... *whack* first staple in. *whack* next one in. Slowly but surely, maintaining professional levels of alignment, equal spacing on the staples, and having a great conversation with the rainbow unicorn kitty (who knew they could talk?) I got the first piece in place. What a relief. The kitty thinks it's sparkly, and it looks like a disco. We need some better music. But we decide to put up more, to really complete the theme. Then when everyone else shows up it will be a real party. Next piece of barrier cut. *whack*whack*whack* staples going in. Let me tell you, when this stuff touches your skin - it's like the fire of a thousand suns. All that reflective power must concentrate the reflected energy into one tiny little spot. It even sizzles a little bit. *whack*whack*whack* a few more staples in, and the second barrier is up. Look kitty - it looks like a spaceship! Bet the guys on the moon didn't have it this good. I slide underneath the area with the reflective barrier and I swear the temperature dropped 15 degrees. NO JOKE. Lying there was like heaven, if heaven was 120 degrees, dark, and itchy. Kitty says the party is canceled... but I can't find kitty anymore. Oh well, real friends are hard to come by, and rainbow unicorn kitties are too needy anyway. I happen to like this music anyway. All jokes aside, you could literally feel the temperature change between the area with the barrier and the area without. It is not fun to put up, Imagine working with a 4-foot wide piece of silver saran wrap - without all the stretch. If you get it lined up just right, you can get it installed amazingly tight and it's quite impressive. I used 1/2" staples, and they held amazingly well, even with all the tugging and fussing I was doing to get it in place. If I didn't get it just right, the stuff doesn't tear easily, but with a little effort I could rip it off of the staples and reposition. The material seems to be tear resistant, so rips won't continue if you do mess up and have to pull a staple or two through. Great product, would definitely buy again, once I use up this roll.
Review: Great Product. Easy to work with - This stuff really works! I was surprised on how much heat this blocked. On my west facing roof in the afternoon, the attic side roof was 140 F and this material was 108. North side was 125F roof and 108F material. Meaning the ambient temp of the attic was 108. Also, this material is very durable. It can be quite awkward placing it in the tight spaces of the attic, but its durability limits the chances of tears. However, I would like it to be ~50" in width. Sometimes the rafters are not exactly 16" apart and its tough to get 4 rafters in there. A competitor makes a 51" version of this

## Questions & Answers

**Q: What is the difference between the ultima-foil and the xtreme radiant barrier foil**
A: The Ultima-foil radiant barrier is an aluminum product that blocks 97% of the radiant heat. When crumpled, it behaves like foil in that it retains the shape it is formed into.  Xtreme radiant barrier is a metalized poly that blocks 95% of the radiant heat and it is very difficult to crumple and shape as it tends to open back up and remain flat. Both versions are virtually tear-proof.

**Q: does it help in the winter months with lesser heating bills?  we live in Meadvill PA and have very cold winters.  There is a company trying to tell us it will help keep our heating bills down while keeping the house warmer.**
A: A radiant barrier will absolutely not lower your heating bills if it is placed on the underside of the roof.  Any heat radiated up from your house would be lost once it gets above the attic insulation.  Heat is what moves and radiates, not cold.  A radiant barrier works only when the sun is radiating heat onto your roof.  Any one that tries to tell you a radiant barrier can lower your heating bills by XX dollars is either lying or does not understand heat transfer and building science.  With that said, a radiant barrier will work well to keep your attic cooler in the summer, during the day, if your roof is exposed to a lot of sun.  A thorough air sealing job, well-sealed ductwork, and proper attic insulation will help you be more comfortable and save money in summer and winter, night and day.

**Q: For attic installations of Xtreme, which is advertised as breathable, is it necessary to leave an opening along the entire peak for air to escape?**
A: If you have a ridge vent, then yes, you need to leave an opening of 6 inches on either side of the ridge vent at the peak. If you have any other roof vents (turbines) then you need to cut out an opening below the vents to ensure adequate ventilation. The key when installing a radiant barrier to the underside of the roof rafters is to make sure you don't obstruct any existing inlet and outlet ventilation in order for full attic space ventilation.

**Q: Can I wrap this around the fiberglass only covered hvac return ducts in my attic that have no radiant barrier?  Is it worthwhile?**
A: I guess it would help and you would have to tape the joints.  A lot of work?????? and not sure how much return you would benefit.

### ⭐⭐⭐⭐⭐ It works!
*by L***O on April 26, 2025*

Added this to my attic to hopefully keep my furnace from freezing up on extreme heat days and to save money on ac bills. It’s thick, durable and more easily installed with a helper. It lowered the temp by 10 degrees measured with laser pointer type of device on barrier covered sections vs none. It was hard to install in some areas due to my furnace being in the way, no real floor in most sections and I did it alone.
